以2009—2020年粤港澳大湾区11个城市为研究对象,探讨制造业集聚与区域创新的关系。研究发现,制造业集聚显著提高区域创新水平,可通过提高企业竞争这一路径实现。进一步分析发现,金融业集聚对区域创新发展具有显著的正向关系,金融产业和制造业产融协同集聚显著提高区域创新水平。研究结果表明,制造业集聚加剧产业内部企业创新竞争,带动区域创新发展,且金融业在创新中起到积极的推动作用。指出应鼓励区域企业创新竞争,优化营商环境,为产业融合发展提供保障。  相似文献

Family firms bear two types of agency costs, including type I and type II agency problems, in corporate environmental practices: (1) Outside executives at family firms hesitate to engage in environmental strategies, which can lead to drops in profits; (2) Controlling families employ opportunistically environmental management to achieve their interests. We argue that a primary cause for the agency problems lies on ineffective internal corporate governance at family firms, which can cause loss of managerial (or power) balance between outside executives and family executives. Our findings show that family firms with ownership and strategic control (FSC), which family executives and outside executives monitor and constrain each other, can achieve the highest environmental performance. Moreover, external controls, including product market competition and provincial environmental regulations, substitute effective internal control of FSC. The environmental performance premium of FSC is more prevalent when the production market competition is lower. Family firms with ownership, operational, and strategic control (FOSC) can achieve higher environmental performance within a province with more stringent environmental regulations.  相似文献

There has been a steady growth of goodwill impairments in the Chinese stock market since the adoption of the impairment approach in accounting. The influence of goodwill impairments on a firm’s financial position and profitability give reason to doubt its current and future performance. We examine whether auditors, as a crucial external monitor, identify the information risks of goodwill impairments and express their concerns about financial reporting quality in their audit opinions. Using a sample of firms listed on China’s A-share market from 2007 to 2017, we test the association between goodwill impairments and the type of audit opinion received in the same financial period. Our findings are as follows. First, the probability of receiving a modified opinion increases with the amount of goodwill impairments. Second, the positive association between goodwill impairments and modified audit opinions is driven primarily by earnings management risks. Third, this positive association is more salient when auditors are industry experts and there is no auditor–client mismatch. Fourth, auditors are more sensitive to the amount of goodwill impairments than to their mere existence. Overall, we document that auditors perceive goodwill impairments as a signal of information risks and communicate their concerns to investors to avoid litigation.  相似文献

Organizations increasingly depend on employee efforts to innovate. However, the quality of relationships between leaders and employees may affect the recognition that employees receive for their innovative work behaviors. Drawing from a social cognition perspective, we tested a model in which leader–member exchange (LMX) moderates the impact of employee innovative work behavior on supervisory ratings of employee performance. Results from two multisource studies combining self, colleague, and supervisor ratings consistently showed that employees receive more favorable performance ratings by engaging in innovative work behavior when they have high‐quality LMX relationships. Moreover, we found that this interactive relationship was mediated by leader perceptions of innovative employee efforts, providing support for a moderated mediation model. Implications for the literatures on performance appraisal, LMX, and innovation are discussed.  相似文献

This paper unpacks the dominant conceptualizations of talent management (TM) in contemporary academic publications, and considers these in relation to the increasingly important workforce population of skilled international migrants. It postulates that TM approaches are generally built from a relatively narrow human capital-based perspective wherein organizations focus on readily accessible and immediate skills, ignoring the longer term strategic potential of the international workforce of skilled migrants, particularly for multinational enterprises and other international organizations. Through a series of propositions, the paper highlights how organizations, in strategically using a more comprehensive TM lens rather than a human capital lens in approaching the TM of skilled migrants, could benefit from improved HRM performance over time. It also proposes a research agenda, by which future studies might test, explore, and further develop understanding on a more strategic utilization of skilled migrants in organizations.  相似文献
